I think your doctor is correct. :)I think that the studies you cited showed more about NOT eating lots of red meat than they showed about eating soy.Heavy periods can be distressing, I am sure, but unless the bleeding never stops, there really is no danger. Stay really well hydrated, and know that this shift in your physiology will take some time. If you are asking if I think you need soy or vitamins, my answer is no. Ride the storm, keep taking great care of yourself, and know that your body is working perfectly.
